Hand-Reared Guam Kingfishers Released After Being Extinct In The Wild Since 1988
Species are being lost from the wild at an unprecedented rate, and some of the most threatened ones are being protected by conservation projects that either work with or employ local people in the area where the species remains and use ex-situ conservation practices (outside of the species’ natural habitat) to protect species that can […]
Eight Years Ago, A Switzerland-Sized Hole Appeared In Antarctic Sea Ice – But Why?
Antarctica is no stranger to icy shenanigans – look no further than the giant spinning iceberg, or the “fingers of death” that lurk beneath the surface.

Octopuses Form Hunting Packs With Fish, But Sometimes Sucker-Punch Their Comrades
Mixed-species hunting packs comprised of octopuses and fish have been observed working together in the wild to improve predation success. It’s been thought that the brainy octopuses would naturally lead the pack, but new research suggests that the chain of command may be more complicated than that. Advertisement Hunting with fish is a particularly curious […]
Are Black Holes Really “Frozen Stars”? New Paper Suggests They Might Be
New research has looked at an alternative idea for what black holes are, suggesting that they might not be what we thought. Advertisement Black holes are an enormous source of gravity, “bubbles“, and headaches. Predicted as a result of Einstein’s general theory of relativity, they contain an outer region known as the event horizon – […]
The Pythagorean Theorem Is Actually 1,000 Years Older Than Pythagoras
Pythagoras was a smart guy: sure, he had some pretty rogue beliefs about beans, but the man knew his triangles, something most of us will have become acutely aware of when high school geometry drummed the Pythagorean theorem into our heads. But did the famed philosopher actually come up with the equation he’s most often […]
Why Is NASA Hoping To Shoot Bullets At The Moon And Mars?
NASA’s Langley Research Center has finally presented a plan to learn about the Moon and Mars, by shooting them with specially designed bullets. We can learn a lot about the Moon through telescope observations, and far more from going there ourselves and taking samples. But nothing, according to a proposed NASA project, quite beats going […]
5-Meter Megamouth Shark Meets Human In Video Of Rare Wildlife Encounter
On June 7 of this year, a British diver had a remarkable encounter with a rare and prehistoric shark. Megamouth sharks (Megachasma pelagios) are hardly ever seen alive, but this 5-meter (16.4-foot) behemoth emerged from the depths to star in some truly remarkable footage.

Treatment Including Playing Tetris Helps Reduce PTSD Symptoms In Healthcare Workers
A session of treatment including playing Tetris for just 20 minutes has been shown to reduce the severity of post-traumatic stress disorder (PTSD) symptoms for up to six months in healthcare workers. It’s unclear exactly how the iconic game produces these therapeutic effects, although researchers believe that “mental rotation” – whereby players visualize falling blocks […]
Three Mile Island – Site Of America’s Worst Nuclear Accident – Could Reopen In 2028

Iron At 10 Billion Degrees Seen Around Supernova In New Telescope’s First Discovery
Astronomers are getting unprecedented details of supernova explosions and supermassive black holes thanks to a new space telescope. The X-Ray Imaging and Spectroscopy Mission (XRISM)launched a year ago and researchers have now published its first scientific results – and they are very good. Advertisement XRISM – pronounced crism – is a mission led by the […]
The Latest Idea For Deflecting Threatening Asteroids? X-Ray Pulses
A high-powered pulse of X-rays could vaporize part of an incoming asteroid and change its trajectory in the process, a new study proposes. Whether the approach would be more cost-effective than alternatives under consideration remains to be seen, but questions also need to be asked about the safety of building a suitable instrument in the […]
Hundreds Of Stars Gone Missing? This Could Be Why
